RO TARY SUPPORT FOR EIVlBOSSlNG-MACH INE PLATENS.

SPECIFICATION forming part of Letters Patent No. 757,759, dated April19, 1904.

Application filed March 10,1903l To all whom, may concern Be it knownthat I, HENRY S. MAIDHOF, a

citizen of the United States, and a resident of vtion of the table.

theborough of Manhattan, in the city and State of New York, haveinvented a new and useful Rotary Support for Embossing-Machine Platens,of which the following is a specification. My invention consists ofarotary support for the platens of .embossing-machines on which theimpression member of the die is mounted. i

The object of my invention is to provide a suitable support which may beremovably engaged with the top of the table of the embossing-machine, soas to be rotated thereon, upon which support the platen bearing theimpres sion member of the die may be immovably mounted after it has beenremoved from its seat beneath the male member of the die.

By the use of this device the superfluous portions of the impressionmember of the die may be quickly and accurately cut away by the operatorwithout requiring-the operator to change the position of thetrimming-knife, the operator being permitted to rotate the platentogether with its support, thus bringing all parts of the impressionmember of the die into a position to permit the operator to readily usethe trimming-knife.

A practical embodiment of my invention is represented in theaccompanying drawings, in which Figure l is a partial top plan view ofthe table of an embossing-machine, the platen being shown removed fromits seat on the table and mounted upon the rotary support, the positionof the support and the platen being also represented in dotted linesupon another por- Fig. 2 is an enlarged side elevation of the support,the platen, and a portion of the table. Fig. 3 is a vertical centralsection through the same, showing clearly the manner of securing theplaten immovably to the rotary support and the manner of rotatablymounting the support upon the table. Fig. 4 is a top plan View of thesupport; and Fig. 5 is a top plan View of a portion of the table,showing the socket for receiving the pivot-pintle of the rotary support.

The embossing-machine table is denoted by Serial No. 147,098. .(Nomodel.)

A, and the seat for the platen by a. A gageplate B is represented uponthe top of the ta; ble, which gage-plate is provided with series ofelongated slots 6, having enlarged openings 1; at their outer ends. Theimpression mom-.5 5 her of the die is denoted by C, and it is secured tothe face of the platen D in the usual manner'as, for instance, by glue.This impression member 0 of the die is composed of any suitable materialsuch, for instance, as cardboard.

The platen D is provided on its bottom face with the usual pair ofprojections 01, which are adapted to enter one ,pair of holes orrecesses a in the seat a of the table for holding 5 the platen rigidlyin position when used in connection with the male member of the die.(Not shown.)

The rotary support for the platen D is denoted by E, which support maybe made of 7 wood. This support E is provided in its top surface withtwo series of holes or recesses a, arranged diametrically opposite eachother, one pair of'which recesses is adapted to receive the pair ofprojections 03 on the under face of the platen D for mounting the platenimmovably upon the said rotary support. This rotary support E isprovided on its bottom surface with a downwardly extended pivot-pintleor projection c, which is fitted to enter a hole or recess in the tableA for rotatably mounting the said support upon the surface of the table.7

In the present instance I have shown the bottom of the rotary support asbeing pro 5 vided with a metallic wearing-plate 6 which is securedthereto by screws 6 which wearingplate has the pivot-pintle orprojection 12' formed integral therewith. I preferably locate the holeor recess a in the top of the 9 table A for the reception of thepivot-pintle e of the rotary support near the front of the table Withinconvenient reach of the operator.

To prevent undue wear caused by rotating the support E, I provide awearing-plate F at the top of the hole a which wearing-plate has acentral opening f of sufiicient size to snugly receive "therethrough thepivot-pintle e of the rotary support- This wearing-plate is preferablycountersunk, so that its top will be level with the top of the table,and it is secured in position by suitable fasteningscrews f.

If so desired, the operator may place the rotary support in otherpositions upon the table by inserting the pivot-pintle e into any one ofthe enlarged ends I) of the elongated slots Z) in the gage-plate B.

The operation of my invention is as follows: The impression-platen, withthe blank thereon, which is to form the impression portion of the die,is first placed in position in its seat a and the male portion of thedie, which is not shown herein, is depressed, forming an impression inthe impression member of the die. The platen is then removed and placedupon the rotary support E. The support E is then rotatably mounted onthe table. The operator then proceeds to cut away the superfluousportions of the impression member of the die. This may be done veryrapidly and accurately, thus insuring a superior quality of work bybringing different portions of the impression member into position to beoperated upon without causing the operator to change the position of thetrimming-knife. The platen is also held Very steadily, which cannot bethe case when the projections on the bottom of the platen are caused torest upon the table while the operator is doingthe work, as hasheretofore been customary.

The rotary support is shown as being provided with a plurality of pairsof holes or recesses e to enable it to be used in connectionwith platensof varying sizes, the projections on small platens being made closertogether than on the larger ones.

It is evident that changes might be made in the construction andarrangement of the several parts without departing from the spirit andscope of my invention. Hence I do not wish to limit myself strictly tothe structure herein set forth; but

What 1 claim is The combination with an embossing-machine table, of aplaten-support rotatably mounted thereon, said support having aplurality of pairs of holes in its top surface arranged diametricallyopposite each other, the holes of one pair being at adifferent distancefrom each other than the holes of another pair, the said holes beingfitted to receive pairs of projections on platens.

In testimony that I claim the foregoing as my invention I have signed myname, in presence of two witnesses, this 7th day of March, 1903.
